'Right Hand' in the Bible

He showed me Joshua the high priest standing before the angel of Yahweh, and Satan standing at his right hand to be his adversary.

In that day I will make the chieftains of Judah like a pan of fire among wood, and like a flaming torch among sheaves; and they will devour all the surrounding peoples, on the right hand and on the left; and Jerusalem will yet again dwell in their own place, even in Jerusalem.
